How to Make a Toy Rowing Boat

Here is an easy way to make your own toy rowing boat. A very simple mechanical structure powered by a DC motor and two batteries are shown to make the rowing boat. It really can float and run on water.

Step 1: Step-by-Step Video Instruction:

Step 2: Components/Part Necessary:

1> 1-inch thick Thermocol / Styrofoam
2> 00 sand paper
3> Card board
4> One 3V DC motor
5> One small switch
6> One pulley for the motor
7> Rubber band
8> One big plastic pulley, or you can make your own as shown in the video
9> Iron wires,
10> AAA battery holder.
11> Two AA battery
12> Tools like knife, pliers, soldering iron, aluminum sheet to make clamps and plastic sheet to make the row fins.

Step 3: Mechanical Dimensions:

Step 4: Schematic: Motor and Switch Connection

I did this project with 5 4th graders over a school break, We did this over a 3 day period, 3 hours per day. All of them finished the project - the fastest one finished 45 minutes early - out of the 9 hours. The rest needed all the time allotted. The kids did all of the work except the cutting of the Styrofoam and the bending and drilling off the pulley brackets. I spent an embarrassing amount of time building the prototype - with the an inordinate amount of time spent getting the wire loops to swing without binding. For the end of the wires serving as the oars, make the loops with a centered loop. Don't have them looking like P's - make them centered at the top of the wire - like a balloon on a string. I wish the kids had been with me for the entire project (i.e. while I was building the prototype) because they would have learned so much about problem solving. You need a gauge of wire for the axle of the pulley that will be tight against the pulley - it can't slip. You can't bend the arms until that axle is fixed through the pulley and are fit through the brackets. You and the kids will feel incredibly accomplished when done
